T 0 all whom i! may concern v Be it known that I, SEYED KHALIL, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have'invented certainrnew and useful Improvements in Dioptragraphs, of which the following is a specification.

The invention relates to improvements in dioptra'graphs: lhe term' dioptragraphci is taken from two Greek w ords dioptra and -gr'aph'.=- 1 1 =3- V The object 'of: this machine'is for'the'pur pose of ascertainin'g-- thedioptra'gra-phic angle or angles of any natural' or artificial T1 structure or design or iinpressiom' so-that j with the" -use of a similar instrumentl the lines of such structure; obj ect or impression may -"be reproduced on a iscreembyi setting angles ascertained thef'priinary" machine: The machine willbe usedaforreproducirig finger: prints, cipher *writiiig,"sblvingfalgebraic problems,i:solving geometrical prob? lems, drawing charts and-regular or i rregular outlines generally: For illustration, a finger print is taken-:oma piece of paper and reflected on" a screen by the reflecting {a mechanism of the' dio tra graphz the -refractory' mechanisms of -t h'e dioptragraphmaybe manipulated to register the dimensions i of the lines of the fin ger printhowever ir'- regular suchlines-may be. The-registration of the lines of the finger print;is secured by the proper -manipulation "of "the refractor mechanisms of" the machine, with' the" use of certain standard slides employed therein, v

same correspondents of the samecryptography shouldbe built exactly alike.

the manipulation of the refractory mecha-'- nisms andslides being indexed on the in,- strument so that anyone, even'at a great distance, having a duplicate di'optragraphmay reproduce an e'ziact facsimile of the finger print by a corresponding" manipulation of} his refractorymechariismsand slides, the index registrationsor' angles of-the primaryinstrument having been communicated to him by cable or-otherwise. I empl oy the expression dioptragraphic angle as indig eating the angles at which the refractory mechanisms maybe set, in connection with the adjustment of the standard slides, and it isthis dioptragraphic angle 'which the holder of the primary machine will communicate to the holder of a similar machine for the reproduction on screen of the image -ter impression may be reproduced. i

first reflected'on the screen of the primary machine by the reflector mechanism thereof.

The dioptragraph comprises in its pre- 'fer-red construction a reflector mechanism for impressing on a screen the outlines of the naturalor' artificial object to be reproduced and a refractory mechanism or refractory mechanisms, plus certain standard slides to be used therewith, for ascertaining the dioptragraphic angle of said object as reflected'onto the screen. The machine will be accompanied by a number of different types of interchangeable slides for use'in the refractory mechanisms, these slides having certain-1 lines thereon which in the refractory mechanisms will, by a proper manipulation, be caused to coincide exactly with the outlines of the object subject-matter, so that Witl-i'the use of-similar slides and similar refractory mechanisms set to the'indexadjustiiients of the primary refractory mechanisms, the. exact outline 0. the subject-mat- JTh'e machines will be of two classes, one comprising general machines, all 'of the same detailed construction and accompanied" by the same types of slides having outlines thereon to be arbitrarily adopted as a standard" Generalnmachines may be used for all purposes, but preferably not for cryptography, The machines for cryptography.w I regardas' special machine'sto be built of different designs from the general machines and also of different designs for different correspondents, it being desirable that only' the machines used between the The type of slides for the general machines will be'limited to a certain'number of standard design, while the type of slides for special machines for cryptography, will be adopted secretly between the operators of the same duplicated special machines.

The="reflector mechanism may vary in type, the object of the reflector mechanism beiri to accurately transmitto a screen the particular design in hand, whether it be thatof a finger print, a drawing or other subject-matter. The refractory mechanisms will each be alike and each comprise a barrel' portion having at its front end a suitablelens capable of being tilted or adjusted .On its own axis, means for tilting said bar ..a-mechanisnr;.

The reflector 30 comprises a main hollow metallic casing whose back or rear portion 35 is of rectangular outline and whose front portion 36 is tubular and has at its outer end a glass disk 37 held in place by a bezel 38. The back portion 35 of the reflector casing contains a reflector 39 which is stationary and set at an angle of forty-five degrees from the vertical, being arranged to reflect images through the disk 37 and upon the ground glass disk 40 of the screen 31, one reflected image 41 being thus shown in Fig. 10.

In an upper extension 42 of the portion 35 of the reflector casing, is mounted a prism 43 whose-lower flat horizontal face is directly over the reflector 39 and whose back inclined face is exposed tohave placed thereon an article 44, as aplate film, \card or piece of wood -or other substance, bearing or carryingthe objector design or outlin or f grain, itis desired shall be reflected upon the reflectolg39 and be thereby impressed on or transmitted to the screen, 31L Within said portion 35 of the" reflector casing is positionedan electricJamp 44, said portion 35 hasat' its back'enda door 45 hinged at its lowerhedgeand adapted'to be held in closed position by any suitable latches 46 (Figs, land 11) .....\'I he upperredge of the door 4:5 is flared outwardly, t ,form a ledge or shelfto, support the article 14 when placed on ,thegprisrn shown; in Fig, 8.

The reflector-3O issecured upon a pedestal 48' and the screen 31-v upon a corresponding pedestal, 49'.

The refractor mechanisms 32,.33are in all theirvdet'ails, andin Figs; 2 to 7 1n- :zclusive I have shownin detail the refractor mechanism32, While, inc-Fig. 1 '1 illustrate? in plan both of saidrefractor mechanisms. VVhile describing the refractor mechanism 32 the reference numerals used will be applied .to the illustration of, the refractor mechanism 33, since the parts are the same in both mechanisms. p V

The refractor mechanism 32 compr1ses a maintubular. or barrel portion 50 having at its back end a reflector 51 and at its front end a removable tubular section 52 containing a double convex or other suitable lens 53 held in a band or ring frame 54, which by means ofcentral transverse trunnions 55 is' of a set screw 56 or in any suitable or convenient manner. The main section {.0 contains in its rear portion an electric lamp 57, and said portion is pivotally mounted in the upper portion'of a transverse yoke 58 (Fig. 6). being held therein on transversetrunnions 59 and being tiltable to various angles, as may be required, the degrees of which angles are indexed on the refractor mechanism, .as hereinafter explained. The yoke 58 has a downwardly extending supporting post 60 whose lower end is reduced to form a pivot 61, which is secured in a-vertical hole 62 in the base 34 by means of a washer 63 and nut 64, said washer and nut being within a socket 65 formed in said base 34 at the lower end of said hole 62. The yoke 58 is thus secured-on a vertical pivot and may be swiveled laterally'for the purposeof adjusting the main section 50 and its parts laterallyon a vertical axis .to any desired or 7 required angle, the degree of which angle is,

indexed on the refractor mechanism, as here inafter explained. =The main section 50 is which carry a band frame-69 withinv said main section 50/(Fig. 2).". gThe frame.69 is adapted totightly receive'and carry a band 71 may be removably secured any one of the inclusiveffThe framefldpreferably has a ,frame 70, .within which bymeans ofabezel refractorslides 72(shown in ,Figs.' 12 to '19 rearinwardly extending annular shoulder form, a seat for the slide 72 andafront out-- wardly xtending Iannular shoulder to abut againstfthe front edge of thelband frame. 69, as shown in Fig. 2. The screws-68 extend through an exterior band or ring 73.

andthis part 73, is fastened by horizontal I screws 74 to a sectional ring 75 freely seated in an annular groove in an internally threaded band 7 6, which engages the thread 66 on the aforesaid main tubular'section 50. When the band 76 is adjusted along the forward end of the main, section50 it carries with it, withoutrotating the same,.the sectional rin 75, band 73, screws 68, band 69 and slide 72, this adjustment being fort-he purpose of positioning the slide 72 in .cor-

rect relation to the lens 53 as maybe required in carrying-out my invention, and such adjustment being indexed on the instrument in degrees and minutesb'y means of a scale 77 on the forward tubular lens carryingsection 52 (Fig. 1),an index finger 78 carried bytheband 73 to cooperate with whose shaft 84 is a portion of the adjacent trunnion 55 of the lens carrying frame 54 (Fig. 2), and the means for indexing the angle of adjustment, in degrees and minutes of the lens 53 comprise a disk 85 hearing on its periphery a scale 86, an index finger 8T v secured to the casing section 52 in position to cooperate with said scale 86, said disk 85 being secured on the aforesaid shaft 84, a scale 109 on the face of the wheel 81 and an index finger 110 for said scale. The shaft 82 is mounted in bearings 88 secured to the casing section 52,

The means for tilting the refractor mechanism on a horizontal axis in the yoke 58 comprise a' -manually operative wheel 89 (Figs. 1 and 6), a vertical worm shaft 90 on whose upper end said wheel is secured, and a worm wheel 91 (Figs. 2 and 3) secured on the adjacent trunnion 59 for easing section 50 and meshing with the worm'shaft 90. The rotation of the wheel"89 will obviously result in such tilting adjustmentof the refractor mechanism as may be desired, and the angle of this adjustment is indexed in degrees and minutes by means of a disk 92 connected to rotate with the worm Wheel 91, an index: finger 93 (Fig. 6) -positioned to cooperate 'with a scale 94 on the disk 92, a

scale 95 on the face of the wheel. 89 (Fig. 1)

and an index finger 96 secured on the frame of the yoke '58 and cooperating with said scale9.

The means for adjusting ,the refractor mechanism on a vertical axis through the. 'post 60 and pivot 61, comprise a manually operative wheel 97 (Figs.' 1 and 3), a verti-.

cal shaft 98 on whose upperend said wheel is secured, a worm 99 on the lower portion of said shaft, a worm wheel 100 (Fig. 2) in mesh with said worm, a shaft 101 on which said worm wheel ,is secured, ,a beveled pinion 102 on said'shaft 101 and a beveled pinion 103 on the post 60 and in mesh with the .pinion 102. When the wheel 9715 turned the motion thereof will, through the gearing described, be transmitted to the yoke 58 and the refractor carried thereby, whereby the forward end of the 'refractormay be adjusted toward the right or left with relation to the screen 31, as may be required, and the angle of such adjustment is indexed in degrees and minutes by a disk 104 on the shaft lOlbearing on its periphery a scale 105,21 stationary index finger 106 (F g. 3) Cooperating with said scale, a scale 107 on the face of said wheel 97 and a stationary index finger 108 cooperating with said scale 10?.

T he method of employing the mechanism hereinbefore described may he understood if it. he considered that the ob ect plate 44 of Fig. 8 is the plate shown in Fig. 20, that the object delineated on that plate has been re- .flcctcd onto the screen 31, as shown in Fig.

10. and that the refraet-ors 3.2, 33 are to be adjusted to such angles as that the refractory lines impressed by the proper slides 72 and lenses 53 onto the screen 31 shall exactly coincide with said outline 41 reflected onto the screen from the objectplate 1'4, to the end that said angles and the adjustment of the slide or slides made use of when ascertained by the indexes hereinbefore identified. may he transmitted to another having a similar dioptragraph, so that such person may by following the data lransn'iitted adjust his instrument to reproduce through the lenses thereon and his standard slides, the aforesaid outline 41 on his screen. from which the same may be photographed or otherwise copied. Info]- lowing out this illustration, the objects 1 regular outline 41 having beenreliected onto the screen .31, I insert in each refractor a 1 standard transparent slide 72' of the t shown in '12 hearing an upwardly'extending arc hemispherical line109; I then adjust the slides 72 longitudinally in the refractors and adjustthe refractors andtheinparts manually by the means hereinbefore. described, until therefracted outlines-'pro.-
